Abstract: System and method for examining a file (1) associated with an originating computer (2) to determine whether a computer virus is present within the file (1). The file (1) contains at least one sector. The file (1) is scanned by an antivirus module (3) associated with the originating computer (2). At that time, an identification of each scanned sector, a hash value for each scanned sector, a date of a most recent update to the antivirus module (3), and a version number of the antivirus module (3) are stored into a critical sectors file (4). The hash values can be calculated by an antivirus accelerator module (5). An authentication module (12) affixes a digital signature to the critical sectors file (4). The file (1), the critical sectors file (4), and the digital signature (15) are then transmitted over a computer network (14) to a recipient computer (11). An antivirus module (3'), an accelerator module (5'), and an authentication module (12'), respectively identical to corresponding modules (3, 5, 12) of' the originating computer (2), are associated with the recipient computer (11). All of the file (1) sectors that were scanned by the originating computer (2) are examined by said second antivirus module (3'). Each of these sectors again has its hash value calculated and compared with the hash value of the corresponding sector as stored within the critical sectors file (4). When any calculated hash value fails to match a corresponding stored hash value for any sector, the second antivirus module (3') is commanded to rescan the entire file (1). Additionally, the recipient computer (11) decrypts the digital signature (15) produced by the originating computer (2) to verify the authenticity of the contents of the critical sectors file (4).

Abstract: An infrared spectrometer (100) for the determination of isotopic ratios of gaseous compounds includes a broad-band infrared light source (102), a spectral selector (138), a sample compartment (106), an infrared detector (112), and a processor (114). The spectral selector (138) selectively transmits a wavelength window of infrared light covering a range of wavelengths in which the wavelength window can be selected alternatively to overlap with a wavelength range primarily absorbed by a compound with a first isotope or by the compound with a second isotope. The sample compartment (108) helds a gas sample and includes a gas inlet and a gas outlet. The infrared spectrometer (100) can be used to detect isotopic ratios of carbon dioxide, where enhancement of 13CO2 can indicate metabolic activity of an infection, for example by H. pylori, or of specific enzymes. Preferred embodiments use a particular multipass optical cell (400) that includes a field mirror (404) and a multi-segment objective mirror (406).

Abstract: A cup tool for use with a mandrel of a wellhead isolation tool has a substantially right-angled stepped shoulder over which an elastomeric sealing element is forced by elevated fluid pressures. A top end of the elastomeric sealing element is inhibited from extrusion past the stepped shoulder during the insertion of the mandrel, thereby reducing the risk of damaging the sealing element before the mandrel is fully inserted through the wellhead. Once the sealing element is exposed to elevated fluid pressures, the top end of the elastomeric sealing element is forced upwardly over the stepped shoulder, and extruded into an annulus between the mandrel and a well casing or production tubing to provide a high-pressure fluid seal.

Abstract: A rotor of an induction starting synchronous motor includes permanent magnets and induction coils having both ends short-circuited in a core. The permanent magnets are arranged side-by-side in a longitudinal direction of the core to form a plurality of sets of permanent magnets. Two sets of the permanent magnets form respective poles of the induction starting synchronous motor. The two sets of permanent magnets forming each of the poles are located inclined or slightly shifted in a cross-sectional plane of the core by rotating the two sets of permanent magnets about corners of the permanent magnets nearest the induction coils as rotating axes into directions such that magnetic fluxes induced by the two sets of permanent magnets cancel each other. With this construction, the induction starting synchronous motor can be smoothly started and operated with improved power factor and efficiency characteristics. A slot for receiving the two sets of permanent magnets is preferably formed at its mid portion with a protrusion and a cavity so as not to permit the permanent magnets to contact each other.
